purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...

in the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. acute corneal pain was induced by the local application of hypertonic saline (5 m nacl) on the corneal surface, and the number of eye wipes was then counted for 30 s. subcutaneous (s...
